摘　　要：附加阻尼比是指结构消能减震设计中,阻尼器(消能装置)附加给原结构的有效阻尼比。其作用是吸收或消耗地震波传递到结构上的能量,减小结构的地震反应。从结构力学知识和结构抗震设计规范的规定可知,当结构附加阻尼比时,建筑结构本身承担的地震作用小于不附加阻尼比的结构,且附加阻尼比越大,建筑结构承担的地震作用减少越明显。本文旨在研究不同阻尼比对地震作用的影响,总结其变化规律。The additional damping ratio refers to the effective damping ratio imparted to the original structure by the damper(energy dissipation device)in the design of structural energy dissipation and vibration reduction.Its role is to absorb or dissipate the energy transmitted to the structure by seismic waves,thereby reducing the structural seismic response.Based on structural mechanics knowledge and the provisions of structural seismic design codes,it is known that when a structure has an additional damping ratio,the seismic forces borne by the building structure itself are less than those of a structure without an additional damping ratio,and the larger the additional damping ratio,the more significant the reduction in seismic forces borne by the building structure.This paper aims to investigate the impact of different damping ratios on seismic forces and summarize their variation patterns.
